At VerdeOS, our purpose is simple: to enrich people’s lives by transforming the built environment.

Unlike traditional service providers, we don’t just identify problems and walk away. We create integrated, compounding value for our clients by taking ownership of the building lifecycle—from strategic advice and optimisation through to delivery and ongoing performance.

Across energy and sustainability, safety and compliance, building optimisation, predictive maintenance, and integrated technology solutions, we combine deep technical expertise with operational excellence to deliver smarter, more efficient, and more sustainable buildings.

As VerdeOS continues its rapid growth across Australia, we’re investing heavily in both our people and our technology. This creates exciting opportunities for ambitious engineers who want to make a genuine impact, deepen their technical expertise, and grow their careers alongside a fast-expanding company.

You’ll work on projects that deliver both environmental and business value, using data-driven insights to improve performance and efficiency across large building portfolios.

You’ll have the opportunity to:

• Work hands-on across Fault Detection & Diagnostics (FDD), building optimisation, and data-driven maintenance services.

• Act as the primary client-facing engineer for your assigned projects.

• Develop and refine the analytics, algorithms, and AI tools that power our services.

• Work closely with software developers to help shape the VerdeOS technology platforms.

• Build your expertise alongside experienced specialists, with genuine pathways for career progression.
